A supergiant star collapses during a supernova blowing off 80.080.0% of it's mass. Angular momentum of the remaining star mass is conserved during the mass blow-off, and so the star spins rapidly. If the initial star diameter is 1.951.95 million kilometers, and it collapses to 14.014.0 km, find the resulting angular velocity in radians per second, given the star's initial angular velocity was 1.01.0 revolution per 36.036.0 days.
A small lightweight rocket is attached to a 7-kg disc that is initially at rest. The disc with a radius of 266 mm is connected to a frictionless stationary pivot O via a lightweight rod of length 1.50 metres (top view shown below). The rocked provides a constant 15.0 N force and remains perpendicular to the connecting rod. Assume the disc slides on a frictionless surface. Calculate the magnitude of the reaction force at pivot O 3.0 seconds after the rocket was fired. Give your answer in newtons and round the final answer to two decimal places.
